碳分法制备造纸用氢氧化铝的研究

Research on the Preparation of Aluminum Hydroxide used in Paper-making by Carbon Dioxide Decomposition Technology

以铝酸钠为原料,采用碳分工艺,通过控制碳分、洗涤及干燥的工艺条件,制得了适合于造纸用的高白度超细氢氧化铝。

Aluminum hydroxide used in paper-making was prepared from sodium aluminate by using the technology of carbon dioxide decomposition with controlling the conditions of carbonization,cleaning and drying process.The product with high whiteness and ultrafine particle size was fit for paper-making.
